When you rub the balloon on your hair, or on another similar surface, the balloon becomes negatively charged. The wall itself doesn't have any particular charge, and doesn't conduct electricity. When you place the balloon on the wall, the molecules in the wall polarize, that is, positive and negative charges in the molecule separate and go to opposite sides of the molecule. Opposite charges attract, and like charges repel, and since the negative charges in the molecules are pushed away from the balloon and the positive ones are pulled towards it, the attraction force is greater than the repulsion force and the balloon is held to the wall.

JudyA negatively charged balloon can stick to a wall because the wall may have a slightly positive charge due to the accumulation of positively charged particles like dust. The opposite charges between the balloon and the wall create an attractive force called electrostatic force that holds the balloon in place.
Static electricity: if the balloon is negatively charged, it repels the electrons near it, and so is attracted to the wall near it, which now has a positive charge (since some of the electrons went away).
If the balloon is positively charged, so it attracts electrons in the wall to it, which creates an area of the wall that is negatively charged, and the balloon is attracted to that.

A balloon will stick to a wooden wall if the balloon is charged?
Yes, the balloon can stick to a wooden wall if it is charged. This is because objects with opposite charges attract each other, causing the balloon to stick to the wall due to the electrostatic force.
What makes a balloon stick to the wall?
A balloon can stick to a wall due to static electricity. When you rub the balloon against your hair or a wool cloth, it gains a negative charge. The negatively charged balloon is attracted to the neutral or positively charged wall, causing it to stick temporarily.
Why does a balloon stick to the wall when it is rubbed with wool?
When a balloon is rubbed with wool, the balloon becomes negatively charged and the wall becomes positively charged. Opposite charges attract each other, causing the balloon to stick to the wall. This is due to the electrostatic force of attraction between the charges on the balloon and the wall.
Why does an inflated balloon stick to a wall after being rubbed on a carpet?
When a balloon is rubbed on a carpet, it becomes negatively charged due to the transfer of electrons from the carpet to the surface of the balloon. The wall, being neutral or slightly positively charged, is then attracted to the negatively charged balloon, causing it to stick to the wall due to electrostatic forces.
What happens when a charged balloon is brought close to a wall?
When a charged balloon is brought close to a wall, the charges on the balloon induce an opposite charge on the wall due to electrostatic induction. This causes the wall to be attracted to the balloon. If the charges on the balloon are strong enough, the wall may even stick to the balloon momentarily.
